The operation of our machine will be easily understood from the drawings-anddescription. It isfirst necessary to' set; the'crank pin I at a proper distancefrom the center of? the shaft G so as to regulate the stroke of the piston; I? in the cy1-ifiderB'- TO, 10' this thenut I is retracted on the threaded;

end of the; pin so that: he pin; is: no longer clamped in the slot- By means of; the. hand wheel J the shaft J? and gearwheel J" will rotate soas-to shift'theepinin the slot H. and by means of: the, indicator finger I and thescale'H the stroke ofzthe piston is; regulated so-that at each stroke i-t wil-l deliverthe exact amount ofiliquidrequired for filling a can or other receptacle The nut 15 is then screwed down with-the result that the vcrank pinis firmly secured in positionh I At each downward stroke of the piston liquidis drawn into, the cylinder Bf through the inlet port G and at each upward move ment of .thepistonlan exactly measured quan: tity of liquid is'forced out of'the cylinder and in.tothefoutlehport G thethiee-way plug valve D. being actuated by the. de scribed mechanism in perfect ,synchronism with the movement of the pistonand so that, irrespective of the stroke of the pisto,n,l the ports in the head C are, fully opened and closed and'it will be observed that as both the inletand'o-utlet ports communicate only withthe top of the cylinder the upper part of the cylinderwill always be filled with liquid with no'opportunity for air to ac'cu inulate which would, of course, result in a defective delivery. It will also be observed that for purposes of cleaning-the head C of the cylinder can be promptly detachedfrom the cylinder by 'loosening'the bolts 0" and disconnecting the snap hook K iby the mechani'sin describediin connection with Figs z i and25. I V q The delivery nozzle formsfan important feature of our invention the'plug F screwed intoits threaded'endf and this conduit F and the down.wardly extending-nozzle F are maintained at StlltlIDES full of liquid by means of the liquid seal provided by. the" cup FT, the edges of which, F extend above'the lower edge F? of the It is connected -with the outlet passage by the conduit F which can be readily cleaned, by removing nozzle so that no air can enterthe lower end of the nozzle, while the atmospheric pressure will prevent the outflow of liquid from the nozzle at any time except when liquid is being forced into the nozzle. be, observed that the construction described in connection with F igs'. 20 to 23 provides for the ready detachment and cleaning of all the mechanical parts of the nozzle which is a matter of greatimportance.

It is, or" course, advisable that the cans to-be filled should be supported with their filling orifices close to the plane of the lower end of the delivery nozzle and it is obviously necessary that'the cans should be accurately positioned on; the: conveyor or; rotating table which brings them successively into registry with thedeliveryv nozzle so that their filling orifices will register with the It will also V nozzle during each dwell in the movement 7 the threaded shaft L and a nut M and when it is necessary to change the height of i the table the latch M is withdrawn by means of the handle M and the nut M rotated by means of the handles 1 2 and M until the shaft carrying the table L has been moved up or down to the desired point, when the latch M is again engaged with the slot in the threaded shaft L so that the table I will remain in fixed position. The positioning plate L secured to the top of the base or pedestal L or otherwise spaced from the top of the table, has its outer edge shaped to closely engage and position the cans resting upon the table L and where cans of different sizes and shapes are to be filled it is important that proper positioning plates should be readily attached to the table and this is provided for by the pedestal and wing nut construction illustrated in Fig. 6 and described in connection with this figure.

The drip catcher pan 0 is given, by the mechanism described in Figs. 10, 11 and 13,

rotating table intoregistry with the delivery nozzle and, to prevent breakage of the machine or of some part of it, the connection between the drip pan and its driving mechanism is made yielding so that in case the drip pan in its rotation strikes any object it can remain stationary. This is provided for in the construction shown by connecting the pan with its driving mechanism through the spring supported block 0 normally resting in contact withthe front portion 0 of the rotating sleeve O While the drip catching pan 0 is made disc shaped and provided with a channel 0 to carry off the liquid caught in the pan, tis unavoidable that some liquid wlll be caught upon the edges of the pan and run down over the outside ofthese edges and the ottom of the pan, and to prevent such liquid from accumulating and falling on the ma chine or the cans, we provide the wiper or scraper P with a wiping edge P which fits over the outer edge and the outer bottom of the pan so as to scrape off liquid adhering to these portions and carry it off through the channel P into some receptacle which mayconveniently be'the same receptacle with which the conduit 0 registers, for instance,

' a drip pan resting on the platform S.

The drip catcher is not secured in place otherwise than by the engagement of the block 0 with the flattened portion 0 of the head 0", and it can be readily removed for cleaning by lifting it and its attached tube 0 from the sleeve O Having now described our invention, what we claim as new and desire to secure by Letters Patent, is: I

1. A filling machine having a measuring cylinder and a'piston moving in said cylinder, in combination with inlet and outlet ports connecting with the cylinder atthe top thereof, a downwardlyextending delivery nozzle connected to the outlet port having a hydraulic seal atits lower end to prevent the entrance of air and maintain the nozzle full of liquid, adjustable means for actuating the piston whereby its stroke can be varied at will and positively actuated means for opening and closing the ports operating in timed relation to the movements ofythe piston.

2. In combination with a filling machine comprising a cylinder and a positively actuated piston organized to deliver a liquid to containers, a delivery nozzle having a downwardly extending portion and a cup located below the end thereof having a rim extending around and above the lower end thereof so as to form a liquid seal to prevent the entrance of airor a gravital outflow of liquid therefrom. I

3. In combination with a filling machine comprising a cylinder and a positively actuated piston organized to deliver a liquid to containers a delivery nozzle having a downion wardly extending portion, a cap nozzle d'etachably secured to the lower end of said downwardly extending portion and'a cup detachably supported on said cap nozzle with its upper edge extending around and above the lower end of the main nozzle so as to form a liquid seal therewith.

4. In a filling machine having a measur-' ing cylinder and piston a delivery nozzle and an intermittently moving conveyor for supporting the receptacles to'be filled below the delivery nozzle and successively bringing them into registry therewith, a rotary drip ing cylinder and piston a delivery nozzle and anintermittentlynaoving conveyor for supporting the receptacles to be filled below the delivery nozzle and successively bringing them into registry therewith, a rotary upright sleeve moving in timed relation to the movements of the conveyor, a drip catcher having a drainage tube removably supported 10 istry' therewith, a rotary drip catcher normally moving in timed relation to the movements of the conveyor so as to extend below the nozzle while the conveyor moves to shift the container, and a scraper conduit arranged to Wipe liquid from the edge of the drip catcher as it moves away from below the delivery nozzle and conduct it to a convenient point of delivery.
